(For the time being the focus will be on lists, not heirarchical trees.)

The tricky part of a list controller/view is that you have a controller/view on a sequence. You need to figure out:

1. How to communicate requests for changes to the sequence
2. What those requests are
3. How to communicate a change in the visible portion of the sequence to the view

We assume the sequences in a list are disjoint.

This API set will be updated piecemeal as I am able to further the implementation

Typedefs

Assume for the time being that the model_type is simple:

 typedef std::string                   value_type;
 typedef std::list<value_type>         model_type;
 typedef model_type::iterator          iterator;
 typedef std::pair<iterator, iterator> sequence_type;
 typedef std::vector<sequence_type>    sequence_set_type;
 
 typedef boost::function<void (iterator before, const sequence_set_type&)> monitor_splice_callback_t;

Model

 void splice(iterator before, const sequence_set_type& value);
 void monitor_splice(const monitor_splice_callback_t& how);

View

 void splice(iterator before, const sequence_set_type& value);

Controller

 void monitor_splice(const monitor_splice_callback_t& how);
